IMPROVEMENT IN TOBACCO-PIPES.

Specification forming part of Letters Patent No. 200,030, dated February5, 1878; application filed January 7, 1878.

To all whom it may concern:

Be it known that I, WILLIAM DEMUTH, of

I the city, county, and State of New York, have invented a new anduseful Improvement in Pipes and Cigar-Holders, which improvement isfully set forth in the following specification,

lining in its bowl, composed of flint, feldspar and oluble glass whichare incorporatet 0- getlier au't'l afp'heil to the interior of the bowlin a liquid state, and then permitted to set, whereby the durability ofthe bowl is greatly increased, without increasing the cost of thearticle to any extent.

In the drawing, the letter A designates a pipe, the bowl B of which isprovided with a fire-proof lining, (marked 0.) This fire-proof lining Iform of the following ingredients, viz: Flint one partfelds )ar twoparts and a su clent quantityof soluble lass to fdrm a paste when theflint and feldspar are mixed together therewith. This composition isfireproof, and at the same time adheres to the surface of the articlelined therewith.

In applying my lining to the bowl B, or to the bowl of a cigar-holder, Isimply pour the 11 0 a composition, in semi-liquid form, into the bowl,and after the entire surface is covered therebyI pour the residue outagain. The lining thus formed is then allowed to set or harden, andafter this has taken place the article is ready for use.

My lining is particularly applicable to cheap wooden pipes, and by itsuse the durability of the article is obviously increased, while, byreason of the extreme facility of its application, the least possibleexpense is incurred in efl'ecting the desired object.

It is obvious that the application of the herein-described liningenables me to utilize wood or other material, which, on account of itsliability to ignite or be affected by heat, could not be used heretoforein the manufacture of pipes and cigar-holders.

What I claim as new, and desire to secure by Letters Patent, is-

A tobacco-smoking pipe having its bowl provided with an interiorfire-proof lining composed of flint, feldspar, and soluble glass,substantially as described.

In testimony thatIclaim the foregoingIhave hereunto set my hand and sealthis 2d day of January, 1878.
